Water heater Ⅰ.To our customers Dear Sir: In order to use this machine safely, please read this INTRUCTION MANUAL carefully before using and installation. Heat pump water heater is a professional machine, it may cause damage or hazard when wrong installed, it should be installed by a competent person in accordance with the relevant standards for the country of use.
Water heater Ⅱ.Product Introducing Product Introducing Safe and Reliable Unlike traditional electric water heater, heat pump water heater do not directly generate heat by electricity , it use less electricity to move heat from one place to another , electric circuit is separated from water circuit ,which is also not easy for electric shock, inflammable , explosion and poisoning ! Safer and more reliable! Highly efficient &...
Water heater Ⅲ.Work principle Work principle The low temperature and low pressure refrigerant gas come from the evaporate to the compressor, After the compressor compress it , the refrigerant gas became high temperature and high pressure.Then the gas come into the water condensation into liquid, emit a lot of condensation heat,condensing heat absorbed by water, making the water temperature increased, and then the liquid refrigerant come through the expansion valve, with a fan , the evaporate heat in the air, after all evaporation , the low pressure...

Ⅷ.Installation instructions Water heater Running Test and operation 2.Running test This running test must be performed by professional staff! 1 Overall test can be run if the entire system inspection is conformed to regulations. 1 Connected to power, start the heat pump, host unit delays three minutes then auto-start. For three-phase power supply unit, first check whether the fans and pumps' rotary direction correct or not, if not, immediately shut down the power and adjust phase sequence.
Ⅸ.Maintenance Water heater Maintenance Heat pump water heater is a high automatic equipment, please perform regular inspection termly. If the unit can be long-term and efficiently maintenance, the operating reliability and service life will have an unexpected increase. 1.The extra water filters should be cleaned regularly to ensure clean water quality of the system, and to avoid damage caused by dirty water filter blocking.
